Ethereum has experienced a substantial price surge throughout August 2025, raising questions about whether it will follow its historical pattern of September declines. The second-largest cryptocurrency is currently trading above $4,700, representing a 25% increase since the beginning of August and a 76% gain year-to-date.
The price rally has brought ETH close to its all-time high, creating renewed optimism in the Ethereum community. This marks the strongest price performance for ETH since the bull run of 2021.
Data from previous years shows a concerning pattern for Ethereum investors. Since 2016, whenever ETH has posted gains in August, a September decline has followed.
In 2017, Ethereum surged nearly 93% in August before dropping 21.65% in September. The pattern repeated in 2020, with a 25.32% August gain followed by a 17.08% September pullback. Similarly, in 2021, ETH climbed 35.62% in August before falling 12.55% in September.
According to CoinGlass data, since September 2016, Ethereum has delivered an average loss of 6.42% during this month, making it historically the worst-performing month for the cryptocurrency.
Crypto trader CryptoGoos highlighted this trend on X, questioning whether this time might be different for ETH given the changing market dynamics.

Institutional Adoption Driving Growth
One major factor that distinguishes the current market from previous cycles is the strong institutional interest in Ethereum. Spot Ethereum ETFs have attracted approximately $2.79 billion in net inflows during August alone.
This stands in stark contrast to spot Bitcoin ETFs, which have seen around $1.2 billion in net outflows over the same period, according to data from Farside.
Nate Geraci, president of NovaDius Wealth Management, noted a “shift” in flows between spot Ethereum ETFs and spot Bitcoin ETFs, suggesting changing institutional preferences.
Corporate treasury adoption has also expanded dramatically. The total value of Ethereum held by companies with crypto treasuries exceeded $13 billion in early August as ETH’s price climbed past $4,300. This figure has since grown to over $17 billion.
BitMINE Immersion Technologies, led by chairman Tom Lee (formerly of Fundstrat), has established itself as the world’s largest corporate Ethereum holder. The company has accumulated over $6.6 billion in ETH, surpassing major investment and tech firms like ConsenSys.
On Saturday, blockchain intelligence firm Arkham reported that Tom Lee purchased another $45 million worth of Ethereum for BitMINE, further increasing the company’s holdings.
Macro Factors and Price Outlook
Broader economic factors may also influence Ethereum’s price trajectory. Federal Reserve Chair Jerome Powell recently hinted at a possible interest rate cut next month during the Jackson Hole symposium, which many crypto market participants view as a potential bullish catalyst.
These dovish signals from the Fed, combined with improving global risk sentiment, have contributed to deeper institutional interest in cryptocurrencies like Ethereum.
On-chain factors such as increased DeFi activity and protocol upgrades like Pectra have further reduced the liquid supply of ETH and incentivized longer-term holding, creating additional support for price growth.
Despite the historical September weakness, some analysts maintain bullish outlooks. Standard Chartered Bank has forecast Ethereum to reach $7,500 by the end of 2025, with longer-term targets of $12,000 in 2026 and $18,000 by 2027.
Tom Lee told CNBC on August 13 that he expects Ethereum to “keep charging ahead” with upside propelled by ETF inflows and institutional adoption, potentially pushing the price above $7,000.
Bitcoin’s market dominance has fallen 5.88% over the past 30 days to 58.19%, which market participants typically attribute to capital rotating into other cryptocurrencies, including Ethereum.
Interestingly, even though September has historically seen losses for ETH, the cryptocurrency posted gains in each of the following three months in both 2016 and 2020. If Ethereum can buck its September curse this year, a bullish fourth quarter may be on the horizon.
With September approaching, investors are watching closely to see if this time will be different for Ethereum given the unprecedented level of institutional investment and corporate treasury holdings.
